Type: MCQ-numerical-Medium
A particle is thrown at angle 45° with the horizontal. If it remains in the air for 1 s, what was its initial velocity?
A
9.8 m/s
B
6.93 m/s
C
19.6 m/s
D
8.49 m/s
Correct Answer
Option B
Detailed Explanation
The time of flight T is given by T = (2u sin θ) / g. Given θ = 45° and T = 1 s, solving for u gives u = 6.93 m/s.
